I really need help on this, I don't quite understand what I am doing :.)

Factor and show work

f ( x ) = 9 x 3 + 2 x 2 − 5 x + 4
g ( x ) = 5 x 3 − 7 x + 4
what is f ( x ) − g ( x ) ?

Subtract the two equations

f(x) - g(x)

(9x3 + 2x2 - 5x + 4) - (5x3 - 7x + 4)

9x3 + 2x2 - 5x + 4 - 5x3 + 7x - 4

4x3 + 2x2 + 2x
